Curious question here: If you take the screenshot you get from WOW and open it up with photoshop/gimp/paint and save it now as PNG or different format, would it be possible to degrade the quality of the dots rendering it useless to be tracked?
- shawnz 14y agoPNG is a lossless format and will not cause the image data to change whatsoever upon saving. JPEG, on the other hand, is a lossy format, but until more is known, it's impossible to say whether or not this secret data (if that's what it really is) happens to be muddled by the lossyness of JPEG's algorithm.
- markszcz 14y agoThanks. You got me thinking in the right direction and I found a Wiki page that talked about image formats and if they are lossy or lossless. http://en.wikipedia.org/wiki/Image_file_formats http://en.wikipedia.org/wiki/Image_file_formats I found it interesting and wanted to share.
- makomk 14y agoProbably not. It looks like this might be doing something clever and possibly relatively robust in the frequency domain, though the details haven't been reverse engineered yet.
